Mikrotik R11eL-FG621-EA Internal Wired Mini PCI Express Green

The MikroTik R11eL-FG621-EA is an internal mini PCIe LTE modem offering up to 300 Mbps throughput. It is an economical upgrade of the previous R11 LTE6 model, providing the same data rates and features at a lower price. The module is manufactured for EMEA, APAC and Australia markets and supports common frequency bands including the B28 band. The card is fully compatible in form factor with full-sized LtAP devices and can be recognized by any RouterOS device when inserted into a PCIe slot or connected via a USB adapter.

Advantages

The R11eL-FG621-EA supports carrier aggregation to combine multiple LTE bands for improved throughput and responsiveness in congested networks and better performance at the edge of coverage. It delivers up to 300 Mbps and maintains the same functionality as the previous R11 LTE6 modem while offering a lower cost. The module’s frequency support includes widely used regional bands such as B28, making it suitable for deployments in EMEA/APAC/Australia.

Suitable for

• Upgrading LtAP and other RouterOS-based systems with a mini PCIe slot
• Rural or suburban locations where carrier aggregation improves throughput
• Embedded network devices requiring internal LTE connectivity

Key specifications

• Form factor: Mini PCI Express (internal)
• Peak speed: up to 300 Mbps
• Regions: EMEA / APAC / Australia
• Supported bands: includes B28 (others depend on regional firmware/carrier)
• Compatibility: Fully form-compatible with full-sized LtAP; recognized by RouterOS devices via PCIe slot or USB adapter
• Brand: MikroTik
• MPN: R11eL-FG621-EA

How to use

Install the R11eL-FG621-EA into a device with a compatible mini PCIe slot or use a suitable USB adapter if required. After physical installation, configure the modem in RouterOS: enable the modem interface, set the APN and other operator settings provided by your carrier, and verify network registration. If using an LtAP, ensure the card is placed in the full-sized LtAP slot for guaranteed form-factor compatibility.

Recommendations

For best results, verify that your mobile operator supports the module’s bands in your area and enable carrier aggregation if available. Use an antenna suitable for the supported frequency bands and place the device to maximize signal reception, especially in rural or weak-signal environments.
